A Secret Service agent assigned to US Vice President JD Vance’s protective detail has been placed on administrative leave while the agency investigates suspected unauthorised disclosures to the media. The case matters because information about a protectee’s travel and security arrangements can create operational and personal safety risks, and could lead to disciplinary action or a criminal inquiry.

Officials reportedly identified an employee believed to have provided information for a recent MS NOW report about frustration within Vance’s security team over his family’s travel demands. The agency’s internal affairs unit is conducting the review; it remains unclear whether the agent will face administrative penalties or criminal charges. The Secret Service said conduct that could compromise a protectee’s safety would not be tolerated.
